Abstract: A postage metering system includes primary accounting structure and non-secure printing structure. The primary accounting structure includes a primary computer which includes structure for sequentially metering respective postage values for printing on respective sheets, structure for detecting a plurality of fault conditions, and structure for disabling the metering structure when the detecting structure detects a selected fault condition. The non-secure printing structure includes a printing module and a printing computer. The printing module includes printing apparatus and structure for sequentially feeding thereto each sheet of a batch thereof having a predetermined plurality of sheets. The printing computer includes structure for transmitting a first request for connection of the printing structure in communication with the primary accounting structure for receiving therefrom respective postage values for printing on respective sheets.

Abstract: A method and system for authenication of communications. More particularly the subject application discloses a method and apparatus whereby a third party may validate that a communication is an authentic communication from a second party sent with the authorization of a first party. For example, the third party may be a postal service, the second party may be a mailer, and the communication may be a postal indicia showing that a mail piece has been properly franked. The first party and the second party share an encryption key, or a series of keys. The first party also has a second encryption key which the third party has the ability to decrypted. In the subject invention the first party encrypts a key shared with the second party with the first party's second key and transmits this to the second party. The second party then uses its copy of the key to encrypt information and appends its encrypted information to the message received from the first party and transmits all this to the third party.

Abstract: Apparatus for printing, folding, and sealing a one-piece form sheet to prepare a self-mailer. The apparatus includes a substantially conventional printer, which may be a laser printer, suitable for use with a personal computer. The printer is mounted above and outputs printed form sheets downwards to a folder sealer for folding and sealing to prepare a self-mailer. The folder sealer includes a folder having a central and peripheral rollers and curved, one-sided, open buckle chutes for folding the form sheet and delivering it to a transport which extends under the printer. The folder sealer also includes moistening apparatus for moistening areas on the form sheet to which a remoistenable glue has been applied.

Abstract: An improvement in a spur gear mechanism having a pair of engageable spur gears, a device for rotating the gears in one direction only, and a device for engaging and disengaging the gears. The improvement includes a chamfer on the top, circumferential surface of each tooth each of the gears. The chamfer starts at the working surface of the gear tooth and extends inwardly toward the juncture of the pitch line of the gear and the non-working surface of the gear tooth, whereby the opposing teeth of the engaging gears do not prevent the re-engagement of the gears when the gears are brought together for engagement.

Abstract: An automated mailing system includes a postage value determining system processor, a scale for providing weight indicative signals, a keyboard for operator entry of information relating to a determination of postage, and a plurality of peripheral devices. A peripheral controller interface establishes communications links with the peripheral devices. An incompatible systems interface interconnects a serial communications bus of the system processor and the peripheral controller interface. The incompatible systems interface includes a processor programmed to receive, decode and transmit information from or to the system processor along the serial bus and load or receive information from or to the peripheral controller interface along parallel lines. The communication timing constraints of the serial communications bus for receipt of data signals by the system processor do not permit monitoring of the data transmission by the incompatible systems processor.
